Description of the Related Art

[0002] In general, a DVR has a construction to convert an image taken by CCD (Charge Coupled Device) camera into digital signals and storage them in a memory. When it replays a stored image, it reads the digital signals corresponding to the image, converts them into an analogue image and displays the analogue image on a monitor so that a user can see. Meanwhile, the data of an image to be stored in the memory is desirably as small as possible. Therefore, DVR manufacturers try to reduce the data amount of an image to be stored through various methods, such as by developing codec (coder/decoder) technologies in their own ways to reduce the number of frames, by lowering image quality, etc. in order to reduce the data amount of an image to be stored.

[0003] However, conventional DVRs applying the above methods comprise a main body having a memory to store data, a monitor having a display screen, a keyboard to apply desired photographing conditions while a user sees the monitor, as needed, and a state imaging device (mostly CCD) to photographing an image and sending it to the main body. Accordingly, they require a large space where the foregoing components can be provided and also human power to install the foregoing components.

[0010] Now, the present invention will be described in detail with reference to the drawings.

[0011] Fig. 1 is a block diagram of the present invention, which comprises an input-output part 10 for receiving and sending audio and video signals, a front panel switch part 20 for instructing various control signals, a micom 30 for recognizing the switch state of the switch part 20, providing the result to a main processor and communicating through serial ports (RS-232), a main processor 40 for recognizing the input signals and giving general storage and output instructions, a converter 50 for receiving output data from the main processor 40 and converting them to analogue signals for output, and a LAN card 60 for driving of the DVR upon receiving the instruction from the main processor 40, as needed for networking. A storage medium 70 is a part for storing data, including, for example, HDD or other storage media. An LCD 80 is a part for displaying video signals according to the instruction from the main processor 40. The micom 30, main processor 40, converter 50, LAN card 60 and storage medium 70 combine to constitute a control part 100 of the DVR.

[0012] The input-output part 10 comprises a video port 11 for receiving video signals from a state imaging device, an audio port 12 for receiving audio signals, a video output port 13, audio output port 14, an Ethernet port 15 for connecting LAN output from the LAN card 60, a serial port (RS-232) for serial communication, a sensor port 16 for receiving a value from a sensor and an alarm port 17 for receiving alarm signals.

[0013] Fig. 2 is a perspective view of the DVR according to the present invention, which comprises a front panel 20 formed of a part of the upper surface of the housing 90, an LCD 80 disposed on a display plate 81 binding to a hinge holder 82 projected on an edge of the upper surface of the housing while covering the front panel switch part 20 and an input-output part 10 extended at the rear surface of the housing 90. The hinge holder 82 is preferably disposed at an interface between the input-output part 10 and the front panel switch part 20.

[0014] Fig. 3 is an enlarged perspective view of the rear side of the main body showing the input-output part of the DVR according to the present invention, which comprises input and output ports 11, 12, 13, 14 for video and audio signals, an Ethernet port 15, a sensor port 16, an alarm port 17, a serial port (RS-232) and a power jack.

[0015] The DVR according to the present invention having the above-described construction, as shown in Fig. 1 and Fig. 3, selectively receives video and audio signals from a desired channel through the video port 11 and the audio port 12. Then, the micom 30 provide an instruction applied by operation of the front panel switch part 20 to the main processor 40. After channel selection, signals from the selected channel are stored in a storage medium 70 and displayed on the LCD 80 at the same time. Alternatively, the signals from the selected channel can be displayed or stored at an external device (for example, video devices, etc) through the video output port 13 and the audio output port 14, as needed. Of course, for the video output, video signals stored in the storage medium 70 are outputted while audio signals are outputted through the audio output port 14 in the analogue state via the converter 50.
